Abstract
A cathode ray tube includes a vacuum envelope having a face plate (1), a continuous phosphor screen (7) formed on the inner surface of the face plate (1), the phosphor screen (7) including a plurality of scanning regions (R1-R15) disposed in rows and column, and a rear plate facing the phosphor screen (7), a scanning arrangement including a plurality of electron guns (15) attached to the rear plate, for individually emitting electron beams toward the phosphor screen, and deflection yokes (16) coupled to corresponding electron guns (15) for deflecting the electron beams. A control section (30) controls the electron guns (15) and the yokes (16) so that one row of the scanning regions is scanned simultaneously while other rows are suppressed.
